Abstract: 1,226,607. Change-speed control. INTERNATIONAL HARVESTER CO. 25 April, 1968 [2 May, 1967], No. 19607/68. Heading F2D. A tractor (not shown) is provided with a hydrostatic gear 2, 3, the ratio of which is automatically varied to constantly maintain full engine power whereby optional utilization of engine power is continuously obtained for working on hilly ground and when ploughing with constant depth of penetration in soils of varying density and resistance. The hydrostatic gear comprises an axial piston type positive displacement pump 2 and motor 3, the motor 3 having a fixed (as shown), are variable (not shown), swash plate 5, and the pump 2 having a variable swash plate 4 linked to the free end of a rod 6 of a differential piston 7 of a follow-up servo, the cylinder 8 of which is pivotally suspended at 9, hydraulic pressure being supplied from a pump 14 to both sides 10, 11 of the differential piston 7 via a throttle duct 12 in the piston 7. A manual speed setting sleeve 22 is axially adjustable on a control rod 21 of the servo for setting the tractor speed, according to a scale 23, and may be locked at 24 in any setting, movement of the sleeve temporarily covering a relief port 19 in the control rod whereby the differentially loaded piston 7 is moved (leftwards for forward ratio) to appropriately adjust the swash plate 4 to the required forward ratio setting, which setting is accordingly established when the relief port 19 is again balanced, i.e. oscillates at the edge of the speed setting sleeve 22. The servo chamber 11 is additionally connected via a duct 18 to a forward-reverse collar 26 which is axially slidable on a fixed sleeve 27 from a neutral position into connection with one or other of control bores 28, 29 which are controlled by a piston 37 of an engine driven centrifugal governor 30. In forward drive, the shifter collar is moved to align its port 25 with the control bore 29 which is closed by the centrifugally moved governor piston 37. If the tractor speed is temporarily reduced, i.e. by hill climbing or dense soil &c., the governor piston 37 is inwardly moved to uncover the control bore 29, thereby reducing the pressure in the servo chamber 11, whereby the swash plate 4 is displaced to the right for reduced forward ratio and hence lower tractor speed, whereby the optimum engine power condition is again restored. In reverse drive, the shifter collar 26 is aligned with the bore 28 such that inward movement of the governor piston 37, on overload engine speed reduction, closes the bore 28 thereby increasing the pressure in the servo chamber 11, whereby the swash plate 4 is displaced to the left for reduced reverse ratio and hence lower reverse tractor speed, whereby the engine condition is again restored as before.

Abstract: 1297950 Shift register input; keyboard circuits W & TAVERY Ltd 2 April 1970 [3 April 1969] 17443/69 Headings G4C and G4H Digital data is entered into a shift register by means of a push button operated encoder. A sensing circuit is connected to the output of the encoder and is effective to clear the contents of the shift register if an actuation of the encoder follows a previous actuation by a period of time greater than a predetermined period. The encoder is a keyboard operated decimalbinary encoder each output of which is connected to a respective shift register 121-124. The sensing circuit comprises two Schmitt trigger circuits 27, 30 and is operative in response to the leading edge of the pulse produced by the push buttons in the encoder to clear the register and in response to the trailing edge of the pulse to generate a shift pulse which is applied to the shift registers and causes the information to be entered from the stores 21- 24. The actuation of the encoder causes the second Schmitt trigger and associated capacitative circuit to block the line along which the clear pulses are transmitted for the aforsaid predetermined period of time so that if the encoder is actuated within this period shift pulses only are generated which pass the information from the encoder output stores 21-24 to the register and shift the information in the register.

Thus, a vehicle on the main road, which is driven to follow the moving wave of amber lamps will not need to suddenly decelerate at the merge point to permit the side road vehicle to join the main road. Prior to the merge point the amber lights are replaced by red lights to give additional warning to the driver of the main road vehicle.
